I installed it all correctly, but when i join multiplayer server (my own server on which i have installed this mod and some content packs) it first sayd that i missed a few item ids, which i thought, was strange, because on singleplayer i all had them.
So i re installed the content packs, and now it gives me a error which looks like it, but this time, no text in the error!
How can i solve this? Really want to play with friends on server!

Could someone help me? I try to install Flan's mod but when I open the game, I get this report:

For the Minecraft Forge do i drop it into my minecraft mod folder or do i create a new folder in my .minecraft folder plz message me how to do it

To install forge, you need WinRar or 7Zip.
1: Open the most recent build of forge (make sure it matches your MC version) with WinRar or 7Zip.
2: open your Minecraft.jar (%appdata% > .minecraft > bin) with WinRar or 7Zip.
3: Drag all files from forge into the jar.
4: Delete META-INF (don't do this if modding a server)
5: Close everything, start MC, if everything went right it should load perfectly, if not and you get a black screen, you didn't kill META-INF or you are using a bad version of Forge.

ummm i with the ye olde mod pack i dont know how to put my cat or dog on the back seat of the biplane and i try pushing the dog into the back seat but it dont work. is there are certain button that i have to use to do it

"All content packs" there's your problem. You need the exact same versions of EVERYTHING as the server. Nothing more nothing less.
